2025 Stumpjumper 15 Comp Bike

The Stumpjumper 15 is here to eliminate all compromise in the trail game. Swallowing bumps like a big bike? Check. Short-travel control, maneuverability, and efficiency? Double check. And what about over-the-top customization to make it perfect for the only rider who really matters—you? Check, check, check.

REVOLUTIONARY CAPABILITY: The Stumpjumper 15 introduces GENIE Shock technology, which combines a lively, playful ride with an infinite downhill feel. This patented air spring technology grants every trail rider’s three wishes: the feel and control of a coil spring, better bottom-out prevention than a standard air spring, and a tunable platform for a playful feel. This innovation ensures your ride is smooth and controlled, no matter the terrain.

ULTIMATE CONTROL: Extensive testing reveals that the Stumpjumper 15 with GENIE provides 57% more traction than the "Bike of the Year" Stumpjumper EVO. This advanced traction control keeps the wheel in contact with the ground longer, delivering significantly improved grip and control across diverse trail surfaces. With 16.3% more shock force management than traditional air spring shocks, the Stumpjumper 15 performs like a longer travel bike, perfect for handling rough terrain and absorbing impacts efficiently.

UNPARALLELED CUSTOMIZATION: The Stumpjumper 15 features six geometry settings, allowing riders to fine-tune the bike's performance to suit their style and terrain. Whether you prefer mixed wheels or 29-inch wheels, the tunable spring curve and various adjustments make this the most customizable bike ever. You can adjust the head angle and bottom bracket height for stability or clearance, ensuring your bike performs optimally in all conditions.

GENIE—The Magic Carpet Ride: GENIE technology is a revolution, combining the linear spring rate of a coil spring in the “bump zone” with the progressive spring rate of an air spring at the end of the stroke. This two-stage system prevents bottom-outs and delivers the best of both worlds—coil and air—with added tunability. With 39% fewer bottom-outs than a standard air spring, GENIE reduces the frequency and severity of impacts, ensuring a smoother ride even on big hits.

REFINED GEOMETRY: The Stumpjumper 15’s geometry is designed to deliver big-bike capability when you need it, agile maneuverability in tight sections, and sprightly, efficient climbing performance. The generous cockpit centers you on the bike, optimizing traction and control through corners. The low bottom bracket, slack head angle, and optimized fork offset maintain stability over rough terrain, ensuring you remain in control on challenging trails.

RIDE YOUR WAY: The seamless integration of the Stumpjumper 15’s benchmark geometry adjustability makes it the most customizable trail bike ever. Six distinct geometry settings allow you to fine-tune performance for all styles and terrains. Whether you need stability or clearance, this bike can be adjusted to meet your specific riding needs.

WHEEL CHOICES: With our aftermarket shock links, you can choose between large wheels front and rear or opt for a 27.5-inch rear wheel for a more responsive and playful ride. Whatever your choice, the geometry remains unchanged, offering flexibility without compromising performance.

CARRY IT ALL: The Stumpjumper 15’s SWAT 4.0 system enhances down tube storage, an innovation we pioneered. This system is the smoothest, most weather-resistant, and flush-fitting design ever, allowing you to carry everything you need for your ride.

MORE RUTHLESS THAN YOU: Our full-suspension bikes are engineered to withstand years of hard riding and are backed by the best support and policies to keep you on the trails. Our unparalleled lifetime, no-questions-asked replacement of suspension pivot bearings for the original owner is just one of the many ways we’ve got you covered.
